Hi All, I am attempting to simulation an inventory model on R and I am having some problems. I believe the problem is when I define my demand rate is stays constant throughout so when I do need to reorder the model does not recognise it as I have the initial supply arrival time set to infinity at the start as no order has been played but I have an if statement saying, if the level falls below a

I am working on the r panel package. Now if i have a function that uses a radiogroup button, and if i attempt to run the function from inside the rpanel menu, i get this error: Error in panel$intname : $ operator is invalid for atomic vectors However if i run the function per se i.e. not from inside the rpanel menu, but by calling it independently, the above error doesn't appear. Here is a

Hello, I've recently discovered a persistent issue with rpanel when running R.app (2.6.1) on Mac OS X 10.4.11. tcltk and rpanel load without any apparent error, and the interactive panels appear to work as expected, however upon closing the panels rpanel has created I get catastrophic errors and R crashes completely. For the most part R manages to crash with dignity and work can be saved, but

Hi all, I wish to use rp.tkrplot from the rpanel package with subplots produced by layout or split.screen. My problem is that I want to use a click function, but I can't work out how to convert the x and y values it produces into the values on the plots as unlike for a single plot they don't match. For example in the following code the (0,0) and (1,1) corners of the bottom left plot

The rpanel package builds on the tcltk package to provide simple interactive controls for R functions, in particular to provide simple forms of dynamic graphics. The intention is to make this form of control particularly easy for R users to implement, with full documentation. The necessary tcltk variables are managed behind the scenes so that users need not be concerned with any

HI Everybody Does anyone know of documentation about different ways of obtaining user input in R. I have used readline() but I wondered is there are sophisticated packages that does things like validate answers or generate selection lists. bets regards Christaan [[alternative HTML version deleted]]

Hi all (again), many thanks for the answer to the optimization problem. All is fine now. The problem now is with kernel estimators in sm. package. I do all the work and the graphics good, but I need the density function data for each point, and I don't know how to get it. The only thing I get is the table at the end of the following sequence: >

Hi, I am pretty new to R. I'm trying run a regression repeatedly, adding a new data point each time, and then storing the predicted Y values. For example, let's say I have 500 data points and I run the regression. I would then like to store the Y value, run the regression again using 501 data points, store the new Y, run the regression with 502 data points, store the Y, and so on. What I

Hi, All I want to implement DSWP Which is used for parallelization of loops. For this purpose, the loop was replaced with a new basic block in main function. And new functions were created and basic blocks of Loop assigned to them.I have checked blocks and branches for Succ and Pred relation and I have not found any problems. However I get the following error: * **opt:

Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value. Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

I'm have a (minor) problem and a question. Problem: The following code creates 5 clusters of dots of different colors. However, I need the second call outside the data.frame call to get the colors to change for some reason. I assume there's an error in the data.frame() call, but I don't know what. Question: Is there is a way to cause the resulting graphic to rotate on it's

HI R users, I would appreciate information/examples/suggestions on building GUIs for R applications. I am currently working on a project that would require the following functionalities : 1) Display a window to the user. Provide a function to scan local drive and choose dataset file. 2) Display the column names for the user to choose the dependent variable and the independent variables. 3) Fit

Hi, I wrote some simple rpanel package script for visual spectral data comparison. At this example i have a three samples and i want to zoom through x and y axis to compare differences between samples. With my script below I can zoom to some data region and add some other spetra to the plot, through text input field. But I can't figure out, how to change axis scaling for all displayed

I have a population of subjects each with a variable which has been captured at a baseline date. Then for many subjects (but not all) an intervention has occurred and the variable has changed at one or more time points after the baseline date. So my dataset consists of a subject ID (x), which may appear several times or just once, a measure (y), and a date of observation (z). I would like to be

Hi R, I have a an excel file with a lot of data. I need to create an user interface in R, which has one single screen. It needs to contain a right pane containing the click buttons for different countries (say). If the user clicks a country, then a chart needs to be created for that country, taking the data from Excel. Is this possible and which package helps me in doing this? Many thanks in

Dear R-help list members, I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent work on the tcltk package, almost everything has gone very smoothly. I'm stymied, however, by the following problem: I want to incorporate a bitmap image, stored as an xbm file, in a widget. To take a simple example, top <- tktoplevel() tkgrid(tklabel(top,
